Used car with diesel engine. Is it worth buying?

Most people who choose a used car choose a car with a gasoline engine. Is it worth investing in a used diesel car?

New diesel cars are often more expensive. In our experience, diesel vehicles depreciate more with age than gasoline vehicles. The reasons are the higher mileage of diesel vehicles and potentially higher repair costs. Customers worry about issues with dual mass clutches, injectors, diesel particulate filters and emergency turbos. However, this downward trend balances out after 6 years and the price difference between diesel and petrol is basically constant,” said Przemysław Wonau, General Manager of AAA AUTO Poland and Member of the Management Board of the AAA AUTO Group.

So is it worth buying a diesel car? Here are the pros and cons.

BEHIND:	Diesels offer more mileage. Usually give 25-30 percent. greater fuel economy than gasoline engines, and the same or better economy than hybrid (gasoline-electric) engines.
VS:	While diesel fuel used to be cheaper, nowadays it often costs the same or even more than gasoline. Diesel is also used in trucks, power generators and many other industrial applications, which thus create demand for oil and therefore increase its price.
BEHIND:	Diesel fuel is one of the most efficient types of fuel today. Because it contains more usable energy than gasoline, it delivers greater fuel economy.
VS:	During the combustion of diesel fuel, nitrogen oxides are released, which must be neutralized in filters that are not used in vehicles with a gasoline engine.
BEHIND:	The diesel engine is more durable to withstand more compression. The record for durability was set by the Mercedes engine, which passed almost 1.5 million kilometers without repair. The durability and reliability characteristics of a diesel engine can help keep your vehicle's higher value when it is sold in the aftermarket.
VS:	If regular diesel maintenance is neglected and the fuel injection system fails, repairs are likely to be more expensive than a gasoline engine because diesel engines are more technologically advanced.
BEHIND:	Due to the way the fuel is burned, a diesel engine delivers significantly more torque than a gasoline engine. As a result, most passenger cars with a modern diesel engine start to move faster and better cope with a towed trailer.
VS:	With the campaign for diesel engines fueled by fraudulent emission measurements, there are fears that vehicles with these engines will be restricted from entering some cities or that environmental taxes will be introduced to increase the cost of operating or registering diesel vehicles.

Diesel technology is constantly being improved. Government pressure on manufacturers of low-emission diesel engines for cars, trucks, buses, agricultural and construction vehicles has led not only to the reduction of sulfur in diesel fuels, but also to the use of specialized catalysts, advanced filters and other equipment to reduce or eliminate emissions. toxic compounds.
